DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

In the following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of various exemplary embodiments. As used herein, theterms “embodiments” and “implementations” are used interchangeably andare non-limiting examples employing one or more of the inventiveconcepts disclosed herein. It is apparent, however, that variousexemplary embodiments may be practiced without these specific details orwith one or more equivalent arrangements. In other instances, well-knownstructures and devices are shown in block diagram form in order to avoidunnecessarily obscuring various exemplary embodiments. Further, variousexemplary embodiments may be different, but do not have to be exclusive.For example, specific shapes, configurations, and characteristics of anexemplary embodiment may be used or implemented in another exemplaryembodiment without departing from the inventive concepts.

Unless otherwise specified, the illustrated exemplary embodiments are tobe understood as providing exemplary features of varying detail of anexemplary embodiment. Therefore, unless otherwise specified, thefeatures, components, modules, layers, films, panels, regions, aspects,etc. (hereinafter individually or collectively referred to as an“element” or “elements”), of the various illustrations may be otherwisecombined, separated, interchanged, and/or rearranged without departingfrom the inventive concepts.

The use of cross-hatching and/or shading in the accompanying drawings isgenerally provided to clarify boundaries between adjacent elements. Assuch, neither the presence nor the absence of cross-hatching or shadingconveys or indicates any preference or requirement for particularmaterials, material properties, dimensions, proportions, commonalitiesbetween illustrated elements, and/or any other characteristic,attribute, property, etc., of the elements, unless specified. Further,in the accompanying drawings, the size and relative sizes of elementsmay be exaggerated for clarity and/or descriptive purposes. As such, thesizes and relative sizes of the respective elements are not necessarilylimited to the sizes and relative sizes shown in the drawings. When anexemplary embodiment may be implemented differently, a specific processorder may be performed differently from the described order. Forexample, two consecutively described processes may be performedsubstantially at the same time or performed in an order opposite to thedescribed order. Also, like reference numerals denote like elements.

When an element, such as a layer, is referred to as being “on,”“connected to,” or “coupled to” another element, it may be directly on,connected to, or coupled to the other element or intervening elementsmay be present. When, however, an element is referred to as being“directly on,” “directly connected to,” or “directly coupled to” anotherelement, there are no intervening elements present. Other terms and/orphrases used to describe a relationship between elements should beinterpreted in a like fashion, e.g., “between” versus “directlybetween,” “adjacent” versus “directly adjacent,” “on” versus “directlyon,” etc. Further, the term “connected” may refer to physical,electrical, and/or fluid connection. In addition, the DR1-axis, theDR2-axis, and the DR3-axis are not limited to three axes of arectangular coordinate system, and may be interpreted in a broadersense. For example, the DR1-axis, the DR2-axis, and the DR3-axis may beperpendicular to one another, or may represent different directions thatare not perpendicular to one another. For the purposes of thisdisclosure, “at least one of X, Y, and Z” and “at least one selectedfrom the group consisting of X, Y, and Z” may be construed as X only, Yonly, Z only, or any combination of two or more of X, Y, and Z, such as,for instance, XYZ, XYY, YZ, and ZZ. As used herein, the term “and/or”includes any and all combinations of one or more of the associatedlisted items.

Although the terms “first,” “second,” etc. may be used herein todescribe various elements, these elements should not be limited by theseterms. These terms are used to distinguish one element from anotherelement. Thus, a first element discussed below could be termed a secondelement without departing from the teachings of the disclosure.

Spatially relative terms, such as “beneath,” “below,” “under,” “lower,”“above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), andthe like, may be used herein for descriptive purposes, and, thereby, todescribe one element's relationship to another element(s) as illustratedin the drawings. Spatially relative terms are intended to encompassdifferent orientations of an apparatus in use, operation, and/ormanufacture in addition to the orientation depicted in the drawings. Forexample, if the apparatus in the drawings is turned over, elementsdescribed as “below” or “beneath” other elements or features would thenbe oriented “above” the other elements or features. Thus, the exemplaryterm “below” can encompass both an orientation of above and below.Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90degrees or at other orientations), and, as such, the spatially relativedescriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particularembodiments and is not intended to be limiting. As used herein, thesingular forms, “a,” “an,” and “the” are intended to include the pluralforms as well, unless the context clearly indicates otherwise. Moreover,the terms “comprises,” “comprising,” “includes,” and/or “including,”when used in this specification, specify the presence of statedfeatures, integers, steps, operations, elements, components, and/orgroups thereof, but do not preclude the presence or addition of one ormore other features, integers, steps, operations, elements, components,and/or groups thereof. It is also noted that, as used herein, the terms“substantially,” “about,” and other similar terms, are used as terms ofapproximation and not as terms of degree, and, as such, are utilized toaccount for inherent deviations in measured, calculated, and/or providedvalues that would be recognized by one of ordinary skill in the art.

Various exemplary embodiments are described herein with reference tosectional views, isometric views, perspective views, plan views, and/orexploded illustrations that are schematic illustrations of idealizedexemplary embodiments and/or intermediate structures. As such,variations from the shapes of the illustrations as a result of, forexample, manufacturing techniques and/or tolerances, are to be expected.Thus, exemplary embodiments disclosed herein should not be construed aslimited to the particular illustrated shapes of regions, but are toinclude deviations in shapes that result from, for instance,manufacturing. To this end, regions illustrated in the drawings may beschematic in nature and shapes of these regions may not reflect theactual shapes of regions of a device, and, as such, are not intended tobe limiting.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which this disclosure is a part. Terms,such as those defined in commonly used dictionaries, should beinterpreted as having a meaning that is consistent with their meaning inthe context of the relevant art and will not be interpreted in anidealized or overly formal sense, unless expressly so defined herein.

As customary in the field, an exemplary embodiment are described andillustrated in the accompanying drawings in terms of functional blocks,units, and/or modules. Those skilled in the art will appreciate thatthese blocks, units, and/or modules are physically implemented byelectronic (or optical) circuits, such as logic circuits, discretecomponents, microprocessors, hard-wired circuits, memory elements,wiring connections, and the like, which may be formed usingsemiconductor-based fabrication techniques or other manufacturingtechnologies. In the case of the blocks, units, and/or modules beingimplemented by microprocessors or other similar hardware, they may beprogrammed and controlled using software (e.g., microcode) to performvarious functions discussed herein and may optionally be driven byfirmware and/or software. It is also contemplated that each block, unit,and/or module may be implemented by dedicated hardware, or as acombination of dedicated hardware to perform some functions and aprocessor (e.g., one or more programmed microprocessors and associatedcircuitry) to perform other functions. Also, each block, unit, and/ormodule of an exemplary embodiment may be physically separated into twoor more interacting and discrete blocks, units, and/or modules withoutdeparting from the inventive concepts. Further, the blocks, units,and/or modules of an exemplary embodiment may be physically combinedinto more complex blocks, units, and/or modules without departing fromthe inventive concepts.

Hereinafter, various exemplary embodiments will be explained in detailwith reference to the accompanying drawings.

FIG. 1 is a perspective view of a display apparatus according to anexemplary embodiment. Referring to FIG. 1, a display apparatus DD maydisplay an image IM through a front surface IS. The front surface IS isparallel to a surface defined by a first directional axis DR1 and asecond directional axis DR2.

A normal direction of the front surface IS, i.e., a thickness directionof the display apparatus DD, is indicated as a third directional axisDR3. A front surface (or a top surface) and a rear surface (or a bottomsurface) of each of members, units, layers, etc., which will bedescribed below, are distinguished by the third directional axis DR3.However, the first to third directional axes illustrated in thisembodiment may be merely examples. Hereinafter, first to thirddirections may be directions indicated by the first to third directionalaxes DR1, DR2, and DR3, and designated by the same reference numerals,respectively.

Although the display apparatus DD having a planar front surface isillustrated as an exemplary embodiment, exemplary embodiments are notlimited thereto. The display apparatus DD may include a curved frontsurface or a solid front surface. The solid front surface may include aplurality of display areas that indicate different directions. Forexample, the solid front surface may include a polygonal column-typefront surface.

The display apparatus DD as seen in FIG. 1 may be a rigid displayapparatus. However, exemplary embodiments are not limited thereto. Forexample, the display apparatus DD may be a flexible display apparatusDD. According to an exemplary embodiment, the display apparatus DD iscapable of being applied to a mobile terminal.

The displayapparatus DD according to an exemplary embodiment may be applied tolarge-sized electronic apparatuses, such as televisions, monitors, etc.,and small and middle-sized electronic apparatuses, such as tabletpersonal computers, navigational units for vehicles, game consoles,smart watches, and the like.

Referring to FIG. 1, the front surface IS of the display apparatus DDincludes an active area AA and a peripheral area NAA adjacent to (e.g.,outside) the active area AA. The active area AA may be an area on whichthe image IM is displayed, and also, an external input TC may bedetected.

The image IM may include a still image and/or a dynamic image. FIG. 1illustrates icon images as an example of the image IM.

The external input TC includes a user's input TC applied from theoutside. The user's input TC includes various types of external inputs,such as a portion of a user's body, light, heat, a pressure, and/or thelike. It is also contemplated that the external input TC may be a nearinput, such as a hovering or approaching input. As seen in FIG. 1, theuser's input TC is illustrated as a user's hand applied to the frontsurface IS.

The peripheral area NAA is an area on which the image IM is notdisplayed, or the external input TC is not sensed even though anelectrical signal is applied. As illustrated in FIG. 1, the active areaAA may have a rectangular shape. The peripheral area NAA may surroundthe active area AA. However, exemplary embodiments are not limitedthereto. For example, the active area AA and the peripheral area NDA maybe relatively designed in shape.

FIGS. 2A to 2D are cross-sectional views of the display apparatus ofFIG. 1 according to an exemplary embodiment. For instance, FIGS. 2A to2D illustrate cross-sections defined by the second directional axis DR2and the third directional axis DR3. FIGS. 2A to 2D are simplyillustrated to explain a lamination relationship of functional panelsand/or functional units constituting the display apparatus DD.

The display apparatus DD according to an exemplary embodiment mayinclude a display unit (or display panel), an input sensing unit (orinput sensing sensor), an anti-reflection unit, and a widow. At leastsome portions of the display panel, the input sensing sensor, theanti-reflection unit, and the window may be formed through a continuousprocess, and at least some portions may be coupled to each other throughan adhesion member. As such, it is to be understood that portions of adisplay apparatus DD formed through a continuous process do not use anadhesion member between adjacent components, e.g., layers, etc., formedthrough the continuous process. FIGS. 2A to 2D illustrate an opticallyclear adhesive (OCA) as an illustrative example of the adhesion member,but exemplary embodiments are not limited thereto. Hereinafter, theadhesion member may include a general adhesive or adhesive agent. In anexemplary embodiment, the anti-reflection unit and the window may bereplaced with different constituents or omitted.

In FIGS. 2A to 2D, a corresponding constituent of the input sensingsensor, the anti-reflection unit, and the window that is formed withrespect to the other constituent through the continuous process, may beexpressed as a “layer.” A constituent of the input sensing unit, theanti-reflection unit, and the window that is coupled to the otherconstituent through the adhesion member, may be expressed as a “panel.”The “panel” may include a base layer providing a base surface, forexample, a synthetic film, a complex material film, a glass substrate,and the like, but the base layer may be omitted in the “layer.” That isto say, the units expressed as the “layer” may be disposed on the basesurface provided by another unit, e.g., an underlying unit.

The display unit, the input sensing unit, the anti-reflection unit, andthe window may be called a display panel DP, an input sensing panel ISP,an anti-reflection panel RPP, and a window panel WP or a display panelDP, an input sensing layer ISL, an anti-reflection layer RPL, and awindow layer WL.

As illustrated in FIG. 2A, the display apparatus DD may include adisplay panel DP, an input sensing layer ISL, an anti-reflection panelRPP, and a window panel WP. The input sensing layer ISL is disposeddirectly on the display panel DP. For the purposes of this disclosure,when “a constituent B is disposed directly on a constituent A” it meansthat a separate adhesive layer/adhesive member is not disposed betweenthe constituents A and B. The constituent B may be formed through thecontinuous process on a base surface provided by the constituent A afterthe constituent A is formed.

The display panel DP and the input sensing layer ISL disposed directlyon the display panel DP may be defined as a display module DM. Anoptically clear adhesive (OCA) is disposed between the display module DMand the anti-reflection panel RPP and between the anti-reflection panelRPP and the window panel WP.

The display panel DP generates an image, and the input sensing layer ISLacquires (or detects) coordinate information of an external input TC(for example, a touch event or touch interaction). Although notseparately shown, the display module DM according to an exemplaryembodiment may further include a protection member disposed on a bottomsurface of the display panel DP. The protection member and the displaypanel DP may be coupled to each other through an adhesion member. Thedisplay apparatus DD of FIGS. 2B to 2D, which will be described below,may also further include the protection member.

The retarder may be a film-type or liquid crystalcoating-type retarder and may include a λ/2 retarder and/or a λ/4retarder. The polarizer may also be a film-type or liquid crystalcoating-type polarizer. The film-type may include an elongation-typesynthetic resin, and the liquid crystal coating-type may include liquidcrystals that are arranged in a predetermined arrangement. Each of theretarder and the polarizer may further include a protection film. Theretarder and polarizer itself or the protection film may be defined as abase layer of the anti-reflection panel RPP.

The anti-reflection panel RPP according to an exemplary embodiment mayinclude color filters. The color filters may have a predeterminedarrangement. The color filters may be determined in arrangement inconsideration of colors of light emitted from pixels provided by thedisplay panel DP. The anti-reflection panel RPP may further include ablack matrix adjacent to the color filters.

The anti-reflection panel RPP according to an exemplary embodiment mayinclude a destructive interference structure. For example, thedestructive interference structure may include a first reflection layerand a second reflection layer that are disposed on (or in) layersdifferent from each other. First reflected light and second reflectedlight that are respectively reflected from the first reflection layerand the second reflection layer, may destructively interfere, and, thus,the external light may be reduced in reflectance.

The window panel WP according to an exemplary embodiment includes a baselayer WP-BS and a light blocking pattern WP-BZ. The base layer WP-BS mayinclude a glass substrate and/or a synthetic film. The base layer WP-BSis not limited to a single layer. The base layer WP-BS may include twoor more films that are coupled to each other through an adhesion member.

Anarea on which the light blocking pattern WP-BZ is not disposed activearea AA of the display apparatus DD.

The light blocking pattern WP-BZ may be a colored organic film, forexample, formed in a coating manner. Although not shown, the windowpanel WP may further include a functional coating layer disposed on anentire surface of the base layer WP-BS. The functional coating layer mayinclude an anti-fingerprint layer, an anti-reflection layer, a hardcoating layer, and/or the like. Hereinafter, referring to FIGS. 2B to2D, the window panel WP and the window layer WL will be simplyillustrated without distinguishing the base layer WP-BS and the lightblocking pattern WP-BZ from each other.

As illustrated in FIGS. 2B and 2C, the display apparatus DD may includethe display panel DP, the input sensing panel ISP, the anti-reflectionpanel RPP, and the window panel WP. A laminated order of the inputsensing panel ISP and the anti-reflection panel RPP may be changed ascan be appreciated in a comparison of FIG. 2B with FIG. 2C.

As illustrated in FIG. 2D, the display apparatus DD may include thedisplay panel DP, the input sensing layer ISL, the anti-reflection layerRPL, and the window layer WL. The adhesion members may be omitted fromthe display apparatus DD, and the input sensing layer ISL, theanti-reflection layer RPL, and the window layer WL may be formed on abase surface provided via the display panel DP through a continuousprocess. Although not illustrated, a laminated order of the inputsensing layer ISL and the anti-reflection panel RPP may be changed, suchas in a manner similar to FIGS. 2B and 2C.

FIGS. 3A and 3B are cross-sectional views illustrating a portion of thedisplay apparatus DD according to various exemplary embodiments. Thedisplay panel DP may correspond to a display unit that will be describedlater. In an exemplary embodiment, an area that corresponds to an areamay mean that the areas overlap each other and have the same surfacearea, but is not limited thereto.

FIG. 4 is a perspective view of an electronic device according to anexemplary embodiment. FIG. 5A is a block diagram of the electronicapparatus of FIG. 4 according to an exemplary embodiment. FIG. 5B is anexploded perspective view of the electronic apparatus of FIG. 4according to an exemplary embodiment. Hereinafter, various exemplaryembodiments will be described with reference to FIGS. 1 to 5B.

According to an exemplary embodiment, an electronic apparatus EAincluding a smart phone will be described as an example. The electronicapparatus EA may display an image IM in the third direction DR3 on adisplay surface FS parallel to each of the first and second directionsDR1 and DR2. The display surface FS on which the image IM is displayedmay correspond to a front surface of the electronic apparatus EA.

The electronic apparatus EA according to an exemplary embodiment maysense a user's input TC applied from the outside. However, this ismerely an example. For example, the electronic apparatus EA may sensethe user's input TC applied to a side surface or a rear surface of theelectronic apparatus EA according to the structure of the electronicapparatus EA. Here, the active area AA may be expanded up to the sidesurface and/or the rear surface of the electronic apparatus EA. Theelectronic apparatus EA according to an exemplary embodiment may bedesigned to have various shapes, but is not limited to a specificconfiguration or shape.

Referring to FIG. 5A, the electronic apparatus EA may include a powersupply module PM, a display apparatus DD, an electronic module EM1, abracket, and an external case EDC (see FIG. 4). The power supply modulePM supplies power for an overall operation of the electronic apparatusEA. The power supply module PM may include a general battery module.

The display apparatus DD is disposed on a rear surface of the windowmember WM. The display apparatus DD may include a display panel unit DPUand an input sensing unit ISU. The display panel unit DPU may correspondto the above-described display panel DP, and the input sensing unit ISUmay correspond to the input sensing layer ISL or the input sensing panelISP. Thus, as described above, the display apparatus DD may display theimage IM and sense the external input TC.

For example, the display panel unit DPU may be configured tosubstantially generate the image IM. The image IM generated by thedisplay panel unit DPU may be displayed on the display surface FSthrough the transmission area TA so as to be visible to an externaluser.

The input sensing unit ISU senses the external input TC applied from theoutside. As described above, the input sensing unit ISU may sense theexternal input TC provided to the window member WM.

Referring to FIG. 5B, the electronic apparatus EA is schematicallyillustrated based on the display apparatus DD. For example, theelectronic apparatus EA may include a window member WM, a displayapparatus DD, and an external case EDC. The display apparatus DD mayinclude an electronic panel EP, a main circuit board MCB, a firstcircuit board CB1, and a second circuit board CB2.

The window member WM may include an insulation panel. For example, thewindow member WM may be made of glass, plastic, or a combinationthereof. A front surface FS of the window member WM may define the frontsurface of the electronic apparatus EA as described above.

The transmission area TA may be an optically transparent area. Forexample, the transmission area TA may be an area having a visible lighttransmittance of about 90% or more, but exemplary embodiments are notlimited thereto.

The bezel area BZA may be an area having light transmittance that isrelatively less than that of the transmission area TA. The bezel areaBZA defines a shape of the transmission area TA. The bezel area BZA maybe disposed adjacent to the transmission area TA to surround thetransmission area TA. The bezel area BZA may have a predetermined color.The bezel area BZA may cover the peripheral area NAA of the electronicpanel EP to prevent the peripheral area NAA from being visible from theoutside. However, this is merely an example. For instance, in the windowmember WM according to an exemplary embodiment, the bezel area BZA maybe omitted. It is also contemplated that the bezel area BZA may includeone or more openings, e.g., electronic module opening EMH, exposing anunderlying electronic module, such as a camera module, a sensor module,etc.

The electronic panel EP includes a front surface IS including an activearea AA and a peripheral area NAA. The front surface IS of theelectronic panel EP may correspond to the front surface IS of thedisplay apparatus DD of FIG. 1. As seen in FIG. 5B, the electronic panelEP may have a rectangular shape having upper and lower sides S1 and S2that extend in the first direction DR1 and are opposed to each other inthe second direction DR2, and left and right sides S3 and S4 that extendin the second direction DR2 and are opposed to each other in the firstdirection DR1.

As described above, the active area AA may be an area that is activatedaccording to an electrical signal. In an exemplary embodiment, theelectronic panel EP may be a constituent on which the image IM generatedby a display panel unit DPU (see FIG. 6A) and an input sensing areaprovided by an input sensing unit ISU (see, e.g., FIGS. 6B and 6C) areprovided.

The first sensing patterns SP1 are electricallyconnected through the first connection patterns BP1.

The first sensing lines TL1 are connected to the first electrodes TE1,respectively. The first sensing lines TL1 connect the first electrodesTE1 to some of the input sensing pads TPD, which correspond to the firstelectrodes TE1, of the first pads T11 and T12, respectively.

In an exemplaryembodiment, each of the second sub lines TL22 may be connected to oneside of each of the second electrodes TE2 disposed in even-numbered rowsof the second electrodes TE2. The other side may be opposed to the oneside in the first direction DR1.

The second electrodes TE2 connected to the second sub lines TL22 of thesecond electrodes TE2 may be electrodes that are not connected to thefirst sub lines TL21. That is, in an exemplary embodiment, each of thesecond electrodes TE2 may be selectively connected to one line of thefirst sub lines TL21 and the second sub lines TL22.

The second sensing lines TL21 and TL22 may transmit the electricalsignal provided through the second sensing pads T21 and T22 to thesecond electrodes TE2 or may transmit electrical signals provided fromthe second electrodes TE2 to the outside through the second sensing padsT21 and T22.

The second electrodes TE2 may receive an electrical signal differentfrom that applied to the first electrodes TE1. Here, the secondelectrodes TE2 may generate electric fields together with the firstelectrodes TE1. The input sensing unit ISU may sense the external inputTC (see, e.g., FIG. 4) through a variation in capacitance formed betweenthe second electrodes TE2 and the first electrodes TE1.

Alternatively, the second electrodes TE2 may receive the same electricalsignal as the first electrodes TE1. Here, the input sensing unit ISU maysense the external input TC (see, e.g., FIG. 4) through a variation ofcapacitance generated in each of the second electrodes TE2 and the firstelectrode TE1 due to the external input TC.

The third electrodes GE are arranged in (e.g., spaced apart from oneanother in) the second direction DR2. Each of the third electrodes GEextends in the first direction DR1. Each of the third electrodes GE mayinclude a plurality of conductive patterns GP and a plurality ofconductive connection patterns GBP.

The conductive patterns GP and the conductive connection patterns GBPare arranged in the first direction DR1. The conductive connectionpatterns GBP are disposed between adjacent ones of the conductivepatterns GP, respectively. However, this is merely an example. Forinstance, the third electrodes GE may be arranged in the first directionDR1, but exemplary embodiments are limited thereto.

The third electrodes GE may be spaced apart from the second electrodesTE2 in a plan view. Each of the conductive patterns GP may berespectively surrounded by a corresponding one of the second sensingpatterns SP2. For instance, the conductive patterns GP may berespectively disposed in openings defined in the second sensing patternsSP2. The third connection patterns GBP may be disposed so that the thirdconnection patterns GBP do not overlap the second connection patternsBP2 in a plan view. This will be described later in more detail.However, this is merely an example. For instance, each of the first tothird electrodes TE1, TE2, and GE may have various shapes, but exemplaryembodiments are not limited thereto.

The third sensing line TL3 is connected to the third electrodes GE,respectively. The third sensing line TL3 connects the third pad T31 andT32 to the third electrodes GE. The third pads T31 and T32 may be spacedapart from each other and respectively disposed on both sides of thedisplay panel pads DPD, but exemplary embodiments are not limitedthereto.

In an exemplary embodiment, the third sensing line TL3 may be providedas a single body. Thus, the plurality of third electrodes GE may beconnected to each other through the single body third sensing line TL3.However, this is merely an example. For instance, the third sensing lineTL3 may be provided as a plurality of third sensing lines TL3 thattransmit the same electrical signal and respectively connect tocorresponding pads of the input sensing pads TPD. The third sensing lineTL3 according to an exemplary embodiment may have various shapes, and,as such, exemplary embodiments are not limited to a specificconfiguration of the third sensing line TL3.

According to an exemplary embodiment, the third sensing line TL3 isconnected to one side of a portion of the third electrodes GE, and isalso connected to the other side of the remaining electrodes of thethird electrodes GE. For example, the third sensing line TL3 may beconnected to a portion of the third electrodes GE at a left side of thesecond area AA2 and connected to the remaining electrodes of the thirdelectrodes GE at a right side of the second area AA2. This will bedescribed later in more detail.

The third sensing lines TL3 may transmit an electrical signal providedthrough the third pads T31 and T32 to the third electrodes GE. In anexemplary embodiment, the third sensing line TL3 may transmit anelectrical signal different from that transmitted by each of the firstand second sensing lines TL1 and TL2.

For example, in an exemplary embodiment, the third sensing line TL3 mayreceive a ground voltage. Thus, the third electrodes GE may maintain theground voltage. The third electrodes GE may prevent a parasiticcapacitance from being generated between the electrical constituentsprovided in the display panel unit DPU and the first or secondelectrodes TE1 or TE2. Thus, even though the input sensing unit ISU andthe display panel unit DPU constitute one electronic panel EP, anoccurrence of noise in the input sensing unit ISU due to the displaypanel unit DPU may be stably prevented (or at least reduced) to improveelectrical reliability and sensitivity of the input sensing unit ISU.

The input sensing unit ISU according to an exemplary embodiment mayinclude a plurality of row electrodes CLE sequentially arranged in adirection opposite to the second direction DR2. Each of the rowelectrodes CLE may be defined by the second electrodes TE2 and the thirdelectrodes GE. For example, one row electrode CLE may be constituted byone second electrode TE2 extending in the first direction DR1 and thethird electrode GE including a conductive pattern GP surrounded by thesecond sensing pattern SP2.

According to an exemplary embodiment, in one row electrode CLE, one sideand the other side, which are opposed to each other in the firstdirection DR1, may be connected to sensing lines different from eachother. For instance, one side of one row electrode CLE may be connectedto one of the second sensing lines TL21 and TL22 and the third sensingline TL3, and the other side may be connected to the other of the secondsensing lines TL21 and TL22 and the third sensing line TL3.

For instance, when one of the second sensing lines TL21 and TL22 isconnected to a left side of the second electrode TE2 of one rowelectrode CLE, the third sensing line TL3 may be connected to a rightside of the third electrode GE of the same row electrode CLE. Here, thesensing lines may not be connected to the right side of the secondelectrode TE2 and the left side of the third electrode GE.Alternatively, when one of the second sensing lines TL21 and TL22 isconnected to the right side of the second electrode TE2 of one rowelectrode CLE, the third sensing line TL3 may be connected to the leftside of the third electrode GE of the same row electrode CLE. Here, thesensing lines may not be connected to the left side of the secondelectrode TE2 and the right side of the third electrode GE.

As illustrated in FIG. 6C, in an input sensing unit ISU_P, each of thethird sensing line TL3P and the third pads T3P may be provided inplurality. The plurality of third sensing lines TL3P and the pluralityof third pads T3P may be connected to corresponding third electrodes GE,respectively. As described above, the plurality of third sensing linesTL3P and the second sensing lines TL21 and TL22 may be alternatelyconnected to the sides of the third electrodes GE, to which the secondsensing lines TL21 and TL22 are not connected. Here, the thirdelectrodes GE may receive electrical signals for sensing the noise inthe active area AA to sense whether the noise due to a position occurs.According to an exemplary embodiment, the input sensing unit ISU_P maybe designed with various structures, and, as such, exemplary embodimentsare not limited to a specific configuration of the input sensing unitISU_P.

FIGS. 7A and 7B are plan views of input sensing units according tovarious exemplary embodiments. For instance, FIGS. 7A and 7B illustrateschematic plan views of input sensing units ISU_N and ISU_H according tovarious exemplary embodiments. As described above, although each of thefirst and second lower sub lines TL11 and TL12, the first and second subsensing lines TL21 and TL22 includes the plurality of lines that aredivided to be respectively connected to the corresponding pads T11, T12,T21, and T22, for convenience of description, each of the first andsecond lower sub lines TL11 and TL12, the first and second sub sensinglines TL21 and TL22, and the corresponding pads T11, T12, T21, and T22is shown as a single grouped line or pad. Hereinafter, the presentdisclosure will be described with reference to the accompanyingdrawings.

As illustrated in FIGS. 7A and 7B, the input sensing units ISU_N andISU_H may have various shapes. For example, Referring to FIG. 7A, aninput sensing unit ISU_N may include a predetermined notch part NT. Thenotch part NT may be defined in the base substrate BS or one side of thedisplay panel unit DPU (see FIG. 6A). In an exemplary embodiment, thenotch part NT may be defined by recessing a portion of an upper side ofthe base substrate BS that extends in the first direction DR1, in anopposite direction of the second direction DR2.

Since the notch part NT is defined, a portion of the first electrode TE1and a portion of the third electrode GE may be removed from the inputsensing unit ISU of FIG. 6B. At least one of the row electrodes CLE mayextend via the notch part NT. In an exemplary embodiment, the rowelectrode CLE disposed at the uppermost side may pass through the notchpart NT.

For example, a portion of the first electrode TE1 may have a surfacearea or length less than that of an area spaced apart from the notchpart NT due to the notch part NT. The first electrode TE1, which isspaced apart from the notch part NT in the second direction DR2, mayhave a length and surface area less than those of the other firstelectrodes TE1 spaced apart from the notch part NT in the firstdirection DR1.

Also, for example, a portion of the second electrode TE2 may be dividedinto left and right portions with respect to the notch part NT. Thesecond connection pattern BP2N, which connects the second sensingpattern SP2 adjacent to the left side of the notch part NT and thesecond sensing pattern SP2 adjacent to the right side of the notch partNT, of the second electrodes TE2 may extend along an edge of the notchpart NT. Thus, a portion of the second electrode TE2 may be electricallyconnected through the second connection pattern BP2N even though some ofthe second electrodes TE2 are separated by the notch part NT.

Also, for example, a portion of the third electrodes GE may be dividedinto left and right portions with respect to the notch part NT, like thesecond electrodes TE2. Thus, the conductive connection pattern GBPNadjacent to the notch part NT may extend along an edge of the notch partNT to connect the two conductive patterns GP, which are spaced apartfrom each other with the notch part NT therebetween in the firstdirection DR1, to each other. Thus, a portion of the third electrode GEmay be electrically connected through the conductive connection patternGBPN even though some of the third electrodes GE are separated by thenotch part NT.

As illustrated in FIG. 7B, the input sensing unit ISU M may include apredetermined hole MH. The hole MH is defined in the first area AA2 topass through at least the input sensing unit ISU_H. In an exemplaryembodiment, the hole MH may pass through the input sensing unit ISU_Hand the base substrate BS. At least a portion of the electronic moduleEM1 (see FIG. 5A), such as the camera module CMM (see FIG. 5A) or thelight receiving module LRM, may be disposed to overlap the hole MH.

At least a portion of the first electrode TE1, the second electrode TE2,and the third electrode GE may have a shape of which a portion adjacentto the hole MH is removed. In an exemplary embodiment, the hole MH maybe defined between two row electrodes CLE sequentially arranged from theoutermost electrode of the row electrodes CLE.

According to an exemplary embodiment, the hole MH is adjacent to twofirst sensing patterns SP1, two second sensing patterns SP2, and twoconductive patterns GP. Each of the two first sensing patterns SP1, thetwo second sensing patterns SP2, and the two conductive patterns GP thatare adjacent to the hole MH may have a relatively small surface areawhen compared to the corresponding peripheral patterns. Sides, whichface the hole MH, of the two first sensing patterns SP1, the two secondsensing patterns SP2, and the two conductive patterns GP may have curvedshapes extending along an edge of the hole MH.

According to various exemplary embodiments, the input sensing units ISU,ISU_N, and ISU_H having various shapes may be provided. Also, the inputsensing units ISU, ISU_N, and ISU_H having the various shapes may havethe structure in which the second sensing lines TL21 and TL22 and thethird sensing line TL3 are respectively connected at different positionswith respect to a single row electrode CLE. Therefore, the electronicapparatus EA, in which overlapping between the third sensing line TL3and the second sensing lines TL21 and TL22 in a plan view is preventedis provided, and, as such, electrical reliability of the electronicapparatus EA may be improved.

For convenience of description, FIG. 8Aillustrates a right area of four row electrodes CLE1, CLE2, CLE3, andCLE4 of the input sensing unit ISU of FIG. 6B, and a left area isillustrated in FIG. 8B. Also, portions L11, L12, and L2N of theplurality of first sub lines TL21 will be described with reference toFIGS. 7A and 7B.

The first row electrode CLE1 may be connected to one of the secondsensing lines TL21 and TL22 at one side and connected to the thirdsensing line TL3 at the other side. For example, referring to FIG. 8A, aright end GP1R of the third electrode GE of the first row electrode CLE1is connected to the third sensing line TL3. On the other hand, a rightend SP21R of the second electrode TE2 of the first row electrode CLE1may not be connected to the second sub line TL22. The right end SP21R ofthe second electrode TE2 of the first row electrode CLE1 is spaced apartfrom the second and third sensing lines TL22 and TL3. Thus, the thirdsensing line TL3 may be stably connected to the third electrode GEwithout overlapping the second sub line TL22 or the second electrodeTE2.

Referring to FIG. 8B, a left end SP21L of the second electrode TE2 ofthe first row electrode CLE1 is connected to one of the first sub linesTL21.

On the other hand, a left end GP1L of the third electrode GE of thefirst row electrode CLE1 may not be connected to the third sensing lineTL3. The left end GP1L of the third electrode GE of the first rowelectrode CLE1 is spaced apart from the first and third sensing linesTL21 and TL3.

Thus, the overlappingbetween the third sensing line TL3 and the second electrode TE2 may bereduced. In an exemplary embodiment, an interference between the thirdsensing line TL3 and the second sensing line L11 may be prevented toimprove the electrical reliability of the electronic apparatus EA.

On the other hand, a right end SP22R of the second electrode TE2of the second row electrode CLE2 may be connected to one line L21 of thesecond sensing lines TL21 and TL22, and a right end GP2R of the thirdelectrode GE of the second row electrode CLE2 may not be connected tothe third sensing line TL3 and may be spaced apart from the thirdsensing line TL3.

In an exemplary embodiment, the third row electrode CLE3 may have aconnection structure corresponding to that of the first row electrodeCLE1. For instance, a left end SP23L of the third row electrode CLE3 maybe connected to one line L12 of the second sensing lines TL21 and TL22,and a right end GP3R of the third row electrode CLE3 may be connected tothe third sensing line TL3. That is, the left end SP23L of the secondelectrode TE2 of the third row electrode CLE3 may be connected to oneline L12 of the second sensing lines TL21 and TL22, and the right endGP3R of the third electrode GE of the third row electrode CLE3 may beconnected to the third sensing line TL3. A right end SP23R of the secondelectrode TE2 of the third row electrode CLE3 and a left end GP3L of thethird electrode GE of the third row electrode CLE3 may not be connectedto the second and third sensing lines TL21, TL22, and TL3.

The fourth row electrode CLE4 may have a connection structurecorresponding to that of the second row electrode CLE2. For instance, aleft end GP4L of the fourth row electrode CLE4 may be connected to thethird sensing line TL3, and a right end SP24R of the fourth rowelectrode CLE4 may be connected to one line L22 of the second sensinglines TL21 and TL22. That is, the left end GP4L of the third electrodeGE of the fourth row electrode CLE4 may be connected to the thirdsensing line TL3, and a left end SP24L of the second electrode TE2 ofthe fourth row electrode CLE4 may not be connected to the second sensinglines TL21 and TL22. On the other hand, the right end SP24R of thesecond electrode TE2 of the fourth row electrode CLE4 may be connectedto one line L22 of the second sensing lines TL21 and TL22, and a rightend GP4R of the third electrode GE of the fourth row electrode CLE4 maynot be connected to the third sensing line TL3.

According to various exemplary embodiments, the second electrode TE2 andthe third electrode GE3, which constitute the same row electrode CLE,may be respectively connected to the corresponding lines of the secondand third sensing lines TL21, TL22, and TL3 at different positions.Thus, the connection between the second electrode TE2 and the secondsensing lines TL21 and TL22, and the connection between the thirdelectrode GE and the third sensing line TL3 may be designed tonon-overlap each other in a plan view.

Further, according to various exemplary embodiments, an overlap betweenthe third sensing line TL3 and the other sensing lines TL11, TL12, TL21,and TL22, or an overlap between the third electrode GE and other sensinglines TL11, TL12, TL21, and TL22 may be reduced or prevented.

The mesh lines may include a first mesh line MSL1 extendingin a first diagonal direction DR4 crossing the first direction DR1 andthe second direction DR2 and a second mesh line MSL2 extending in asecond diagonal direction DR5 crossing the first diagonal direction DR4.

The first and second mesh lines MSL1 and MSL2 may be disposed on thesame plane (or layer) and may be connected to each other. The first andsecond mesh lines MSL1 and MSL2 form a first sensing pattern SP1_M, asecond sensing pattern SP2_M, a second connection pattern BP2_M, and aconductive pattern GP_M. Boundaries between the first sensing patternSP1_M, the second sensing pattern SP2_M, the second connection patternBP2_M, and the conductive pattern GP_M may be formed by cutting thefirst and second mesh lines MSL1 and MSL2.

Thus,electrical connection between the second electrode TE2_M and the thirdelectrode GE_M, which independently transmit signals, may be prevented,and, as such, electrical reliability of the electronic apparatus EA_Mmay be improved.

FIG. 12A illustrates a portion of an area of a right end of a first rowelectrode CLE_M1. As illustrated in FIG. 12A, in the first row electrodeCLE_M1, a right end of a third electrode GE_M1 may further extend in thefirst direction DR1 than a right end of the second electrode TE2_M1. Theright end of the third electrode GE_M1 may be connected to a thirdsensing line TL3.

In an exemplary embodiment, the first row electrode CLE_M1 and the thirdsensing line TL3 may be disposed on the same line or layer. Thus, theright end of the third electrode GE_M1 may be directly connected to thethird sensing line TL3. However, this is merely an example. Forinstance, the right end of the third electrode GE_M1 may be integratedwith the third sensing line TL3, but exemplary embodiments are notlimited thereto.

FIG. 12B illustrates a portion of an area of a right end of a second rowelectrode CLE_M2. As illustrated in FIG. 12B, in the second rowelectrode CLE_M2, a right end of a second electrode TE2_M2 may furtherextend in the first direction DR1 than a right end of the thirdelectrode GE_M2.

The right end of the second electrode TE2_M2 is connected to a secondsensing line TL2 through a connection part CP_M. In an exemplaryembodiment, the connection part CP_M is disposed on a layer differentfrom that of each of the second and third sensing lines TL2 and TL3. Thesecond electrode TE2_M2 may be connected to the connection part CP_Mthrough predetermined contact parts CTS. The second sensing line TL2 maybe connected to the connection part CP_M through predetermined contactparts CTL. Thus, the second electrode TE2_M may be stably connected tothe second sensing line TL2 without overlapping the third sensing lineTL3.

According to various exemplary embodiments, overlap between the signallines that transmit the electrical signals different from each other maybe reduced or prevented. Thus, the occurrence of noise due to theelectrical interference between the signal lines may be reduced (orprevented) to improve the input sensing unit having the improvedexternal input sensitivity. In addition, the display apparatus havingthe improved electrical reliability may be provided.
